摘　　要：在对全自动可转位刀片周边磨床早期故障以及失效机理分析的基础上,采用试验方法,对其整机及关键功能部件进行了可靠性研究,获得指数分布下机床的真实故障数据、故障分析结果和磨床的平均无故障运行时间,提出该磨床在今后设计、制造和装配过程中的建议。试验证明,该机床的可靠性指标符合要求,在改进后将获得更高的可靠性指标值。With the method of experiment to study the reliability of whole grinding machine tool and its functional units on the basis of the analysis of its early failures and the failure mechanism. Get the real data of the failures under the exponential distribution, the results of the failure analysis and the value of MTBF, and put forward some suggestions in the process of design, manufacturing and assembly for this machine in the future. The experiment proved that the machine meets the requirement index of reliability, and the value of the index will be higher after being improved.
